This 1859 dated carbine has the standard marking and features. 1,140 of these carbines were manufactured by E. Gwyn and A. C. Cambell's company, the Cosmopolitan Arms Co., to fill an order for the State of Illinois placed through the U.S. Ordnance Department in December of 1861. They were delivered in July 1862. The 5th Illinois Cavalry received over 400 and the majority were used by the 6th Illinois Cavalry during the famous Grierson's Raid that diverted Confederate attention from Grant's Vicksburg campaign.

Fair as refinished. The carbine displays a dark blend of applied blue finish and an artificial brown patina as well as some faint traces of pitting. There is brighter blue finish on the hammer, lever, and breech. The refinished stock has some small pressure marks. The lock bridle is cracked, but it functions very well. Most of the markings are clear.
